ICSE − Q & A

About the UCM acceleration "confusion", what are you guys writing?
My physics teacher told us to write the acceleration as variable..
Maybe if we support it with logic, we'll get marks

If we have to draw a diagram for Snell's LAW(only the sin i/sin r, rt? cause only one), should we just draw light travelling from a denser to a rarer medium, mark angles of incidence and refraction and state the law, or is there some other diagram??

What purpose is served by the terminals of three way pin plug?

A small suggestion here(You may be doing it already)

While drawing ray diagrams, try drawing the lens using protractor, and you'll get perfectly equi-convex/concave lenses. I used to draw them using compass and it was a mess.

P.S. Don't forget those tiny little arrow-heads!

A few doubts here: 1. Which definition of "Refractive Index" are we supposed to write? 2. What's the principle of a machine? 3. Energy conversion in Bulb - Is it Electrical to Light OR Light & Heat? I mean, do we need to mention the degraded form of energy too?

Why does the focal length of a convex lens remain unchanged even when half of it is covered ?

I haven't started numericals yet... Any ideas how I should approach them?

Ok so if anyone is so kind enough to tell me when to convert kgf to N or even when g= 10m/s^2 is given, when should we convert. and is it necessary to convert to g from kg when solving for the Work done (Kinetic or potential energy.) I know its a silly doubt, but please help me.

How many chapters have you studied in physics?

Radioactivity is a nuclear phenomenon.comment on the statement.
